• Substrate specificity of isopenicillin N synthase
  作者：George W. Huffman、Paul D. Gesellchen、Jan R. Turner、Robert B. Rothenberger、Harold E. Osborne、F. Dean Miller、Jerry L. Chapman、Stephen W. Queener

  Highly purified isopenicillin N synthase (IPNS) from two sources (naturally occurring in Penicillium chrysogenum and that expressed in Escherichia coli via a cloned gene derived from Cephalosporium acremonium) have been isolated and utilized in vitro to test synthetic modifications of the natural substrate, (L-alpha-amino-delta-adipyl)-L-cysteinyl-D-valine (ACV). A very sensitive procedure utilizing

  两种来源的高纯度异青霉素N合酶（IPNS）（天然存在于产黄青霉菌中，并通过顶头孢霉的克隆基因在大肠杆菌中表达）已被分离并在体外用于测试天然底物的合成修饰（L -α-氨基-δ-己二酰基）-L-半胱氨酸-D-缬氨酸（ACV）。利用一种非常敏感的程序，利用β-内酰胺诱导β-内酰胺酶的合成，来确定ACV类似物是否可以用作IPNS的底物。检查了多种氨基和羧基末端三肽取代，发现它们引起了正的β-内酰胺酶诱导曲线。但是，没有发现这些修饰能够像ACV一样有效地用作底物。由IPNS和三肽类似物反应形成的一种β-内酰胺产物是独立合成的，并具有抗菌活性。在ACV第二个位置修饰L-半胱氨酸残基导致三肽不能用作底物。ACV第三位的D-缬氨酸残基转化为芳香族氨基酸或高负电性残基（如三氟缬氨酸）会导致底物活性消除和酶抑制剂的产生。

  Loose fit: IPNS catalyses the central step in penicillin biosynthesis. Substrate analogues containing L‐homocysteine in place of the natural substrate's L‐cysteine residue are not converted into bicyclic products. Crystal structures for IPNS complexes with two such analogues reveal that the additional CH2 unit affords considerable conformational freedom when these analogues bind to IPNS.

  宽松：IPNS催化青霉素生物合成的关键步骤。包含L-高半胱氨酸代替天然底物L-半胱氨酸残基的底物类似物不会转化为双环产物。具有两个这样的类似物的IPNS配合物的晶体结构表明，当这些类似物与IPNS结合时，额外的CH 2单元可提供相当的构象自由度。

  chemical model of a β-sheet (artificial β-sheet) that dimerizes by parallel β-sheet formation in chloroform solution. The artificial β-sheet consists of two N-terminally linked peptide strands that are linked with succinic or fumaric acid and blocked along one edge with a hydrogen-bonding template composed of 5-aminoanisic acid hydrazide. The template is connected to one of the peptide strands by a turn unit

  本文介绍了 β-折叠（人工 β-折叠）的简单化学模型，该模型通过在氯仿溶液中平行 β-折叠形成而二聚化。人工 β-折叠由两条 N 端连接的肽链组成，这些肽链与琥珀酸或富马酸连接，并沿一个边缘被一个由 5-氨基茴香酸酰肼组成的氢键模板封闭。模板通过由 (S)-2-氨基己二酸 (Aaa) 组成的转向单元连接到肽链之一。1H NMR 光谱研究表明，这些人工β-折叠在CDCl3 溶液中折叠形成明确定义的β-折叠结构，通过平行β-折叠相互作用二聚化。最值得注意的是，所有这些化合物都显示出与折叠和二聚化相关的丰富的 NOE 网络。这些化合物还表现出与折叠二聚体 β-折叠结构的形成一致的化学位移和偶联常数。氨基己二酸单元显示的 NOE 模式和耦合常数与明确定义的转...

  Isopenicillin N synthase (IPNS) catalyses conversion of the linear tripeptide delta-(L-alpha-aminoadipoyl)-L-cysteinyl-D-valine (ACV) to isopenicillin N (IPN), the central step in biosynthesis of the beta-lactam antibiotics. The unsaturated substrate analogue delta-(L-alpha-aminoadipoyl)-L-cysteinyl-D-vinylglycine (ACvG) has previously been incubated with IPNS and single product was isolated, a 2-alpha-hydroxymethyl

  异青霉素N合酶（IPNS）催化将线性三肽δ-（L-α-氨基己二酰基）-L-半胱氨酰-D-缬氨酸（ACV）转化为异青霉素N（IPN），这是生物合成β-内酰胺抗生素的关键步骤。先前已将不饱和底物类似物δ-（L-α-氨基己二酰基）-L-半胱氨酰-D-乙烯基甘氨酸（ACvG）与IPNS一起温育，并分离出单一产物，形成了2-α-羟甲基异青霉素N（HMPen），通过单加氧酶反应模式。ACvG现在已经用IPNS结晶，厌氧IPNS：Fe（II）：ACvG络合物的结构确定为1.15 A分辨率。此外，通过将厌氧生长的晶体暴露于高压氧气中，以1.60A的分辨率获得了对应于双环产物HMPen的结构。根据这些以及其他IPNS结构，以及相关双加氧酶的最新发展，对由ACvG形成HMPen的[2 + 2]环加成机理进行了修订，并提出了逐步的自由基机理。修订后的机制与观察到的转化立体定向保持一致，但更适合于活性位铁原子周围配位几何的明显约束。
